The degree of the arc formed by a central angle is question options: equal to the measure of the angle. has no relationship to the measure of the angle. 1/2 the measure of the angle. 2 times the measure of the angle.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
